The idea of having friend here with her - the threat that wasn't even thinly veiled in that - shut Ali up for now. There was nothing he could do to her that wasn't a thousand times worse when she thought about another of her friends having to suffer it with her, because of her. She thought of Fred and George and Ron - hell, even Percy - and shut her mouth, eyes casting down at her own feet. Not at him. Better not to give him anything that he took as a challenge.
